        noofchild = 0
if noofchild != 0 :   
       formsetlist = []


       for i in range(0, noofchild):

                  uip.budget_amount = x
                  uip.save()

         except budget.DoesNotExist:

                w = budget(account_no = z, account_period = y, budget_amount = x, created_by_login = 'me')
                w.save()
         j=j+1
       pass
       return HttpResponse('thanks')


    else:

     #return HttpResponse(mes)

    return render_to_response('budgetfinalform3.html', {'account_number': c,'period':d,'month':e,'year':f,'formsetlist': formset,'child':child},context_instance=RequestContext(request))

    Uses formset but it looks/sounds like you meant formsetlist:

    return render_to_response('budgetfinalform3.html', {'account_number': c,'period':d,'month':e,'year':f,'formsetlist': formsetlist,'child':child},context_instance=RequestContext(request))
